Ken Smith Pro Formula Guitar Polish for Laquer Finishes, PRO-POLISH5RuppertjilesAugust 17, 2011I used it on my Steinberger bass Hofner copy right before our outdoor summer gigs this year where we had everything from drizzle to blistering heat in direct sun and KS won out. Resists water, perspiration, and looks great. I used Gibson polish for years but this seems superior. Not only went on easy, but doesn't seem waxy (no smear marks when you wipe your skin against it) and has some cleansing properties to it that removed some old grime.
